Ideological opposites to face off in Colombia’s presidential election

Right-wing politician Ivan Duque won the first-round of Colombia’s presidential election on Sunday, setting up a runoff next month against Gustavo Petro, a leftist from the former guerrilla group FARC, per AP.

By the numbers: More than 18.5 million people reportedly cast ballots, the highest turnout in two decades.

The candidates: Duque is chosen candidate of Alvaro Uribe, the country's former president. He's a staunch critic of FARC and the peace deal with the group, per the AP. He plans to change the terms of the agreement, including imprisoning former rebels for war crimes and blocking them from political office.

Petro has galvanized support among young voters infuriated over the country's inequality and sluggish economy. He's running on a populist, anti-establishment platform to overhaul the country's economic policy, hoping to redistribute wealth.
